Can a stroke be missed on MRI?

While the use of brain MRI has increased our ability to detect many types of cerebrovascular disease, our study indicates that MRI using high field strength 1.5-T magnets may still miss large-vessel and small-vessel acute ischemic strokes.

Can a stroke be detected years later?

“Finding silent strokes or other signs of vascular disease is not uncommon as people get older,” Smith said. Silent strokes are much more common than strokes that cause classic symptoms such as face drooping, arm weakness and speech difficulty and affect nearly 800,000 Americans each year.

Can an MRI show if you’ve had a stroke?

MRI can detect brain tissue that has been damaged by both an ischemic stroke and a brain hemorrhage. Also, an MRI is very sensitive and specific in distinguishing ischemic lesions and identifying pathologies that resemble stroke, known as “stroke mimics”.

Do all strokes show up on an MRI?

Past studies have suggested that MRI may not visualize all acute strokes, but few clinical details were included. To better understand the clinical characteristics of strokes not detected by MRI, we collected and reviewed case histories of several patients with acute stroke who had negative MRI scans.
